+This is the 52nd release of NuttX.  This release includes one new port, some
+new drivers and some important bugfixes:
+
+  * NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit.
+    At present, that port includes an OS test configuration and a NuttShell
+    (NSH) configuration with telnet support.
+
+    MMC/SD and Networking support are provided but not thoroughly verified
+    in this release: Current development efforts are focused on porting the
+    NuttX window system (NX) to work with the Evaluation Kits OLED display.
+
+  * A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is
+    available in the source tree (but has not yet been fully verified because
+    I haven't properly connected it to hardware yet).
+
+  * The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and
+    some new networking configurations were added.  The ENC28J60 has not
+    been tested on the STR-P711, however, because of hardware issues (I don't
+    think the USB powered board provides enough power for the ENC28J60 and
+    I don't have the right wall wart yet).
+
+    Along the way, external interrupt support (XTI) was added to the STMicro
+    STR-P711 port and some important bugs were fixed in the STR-P711 SPI
+    driver.
+
+  * Corrected an important UDP reference counting error.  It was not a serious
+    error, but it trigger an assertion was IS a serious error.
